drm/radeon: make MMU_NOTIFIER optional
In cases where MMU_NOTIFIER is not available, userptr will not be
available. Similar to i915, although not making an exception for
CAP_SYS_ADMIN.
The proposed userspace patches for userptr seem to handle the fall-
back properly, so a userptr-less kernel should not be a problem.
